| <div class="block"><code>NMClientAsync</code> handles communication with all the NodeManagers |
| and provides asynchronous updates on getting responses from them. It |
| maintains a thread pool to communicate with individual NMs where a number of |
| worker threads process requests to NMs by using <a href="../../../../../../../org/apache/hadoop/yarn/client/api/impl/NMClientImpl.html" title="class in org.apache.hadoop.yarn.client.api.impl"><code>NMClientImpl</code></a>. The max |
| size of the thread pool is configurable through |
| <code>YarnConfiguration.NM_CLIENT_ASYNC_THREAD_POOL_MAX_SIZE</code>. |
| |
| It should be used in conjunction with a CallbackHandler. For example |
| |
| <pre> |
| <code> |
| class MyCallbackHandler extends NMClientAsync.AbstractCallbackHandler { |
| public void onContainerStarted(ContainerId containerId, |
| Map<String, ByteBuffer> allServiceResponse) { |
| [post process after the container is started, process the response] |
| } |
| |
| public void onContainerResourceIncreased(ContainerId containerId, |
| Resource resource) { |
| [post process after the container resource is increased] |
| } |
| |
| public void onContainerStatusReceived(ContainerId containerId, |
| ContainerStatus containerStatus) { |
| [make use of the status of the container] |
| } |
| |
| public void onContainerStopped(ContainerId containerId) { |
| [post process after the container is stopped] |
| } |
| |
| public void onStartContainerError( |
| ContainerId containerId, Throwable t) { |
| [handle the raised exception] |
| } |
| |
| public void onGetContainerStatusError( |
| ContainerId containerId, Throwable t) { |
| [handle the raised exception] |
| } |
| |
| public void onStopContainerError( |
| ContainerId containerId, Throwable t) { |
| [handle the raised exception] |
| } |
| } |
| </code> |
| </pre> |
| |
| The client's life-cycle should be managed like the following: |
| |
| <pre> |
| <code> |
| NMClientAsync asyncClient = |
| NMClientAsync.createNMClientAsync(new MyCallbackhandler()); |
| asyncClient.init(conf); |
| asyncClient.start(); |
| asyncClient.startContainer(container, containerLaunchContext); |
| [... wait for container being started] |
| asyncClient.getContainerStatus(container.getId(), container.getNodeId(), |
| container.getContainerToken()); |
| [... handle the status in the callback instance] |
| asyncClient.stopContainer(container.getId(), container.getNodeId(), |
| container.getContainerToken()); |
| [... wait for container being stopped] |
| asyncClient.stop(); |
| </code> |

| <p> |
| The callback interface needs to be implemented by <a href="../../../../../../../org/apache/hadoop/yarn/client/api/async/NMClientAsync.html" title="class in org.apache.hadoop.yarn.client.api.async"><code>NMClientAsync</code></a> |
| users. The APIs are called when responses from <code>NodeManager</code> are |

| </p> |
| |
| <p> |
| Once a callback happens, the users can chose to act on it in blocking or |
| non-blocking manner. If the action on callback is done in a blocking |
| manner, some of the threads performing requests on NodeManagers may get |
| blocked depending on how many threads in the pool are busy. |
| </p> |
| |
| <p> |
| The implementation of the callback function should not throw the |
| unexpected exception. Otherwise, <a href="../../../../../../../org/apache/hadoop/yarn/client/api/async/NMClientAsync.html" title="class in org.apache.hadoop.yarn.client.api.async"><code>NMClientAsync</code></a> will just |
